Vacuum MSK-200-SH is an innovative tape casting coater to make a lithium film on copper foil. The coater uses a heatable slot-die and a fixed gap blade on a fixture with precision wheels. Lithium molten will be extruded into the heated slot-die, then cast the melt on the copper foil, which is sucked by the heated vacuum bed. The heated blade will scrape over the melt following the slot-die to form one sheet of precision lithium film after the casting fixture passes through the heated vacuum bed stably. This method may make 15 - 50 micron-thick lithium film in an Ar gas glovebox. SPECIFICATIONS: Power 208-240V, 50/60Hz, (single phase) 2000W Moveable Coating Fixture ( Patent pending) The movable tape casting fixture includes a lithium melting vessel, a heatable slot die and a fixed gap blade, with 4 precision wheels, as shown in the picture on the left. 1. Heating Vessel: Made of SS 316 with dimensions of ID25mm × height 100mm, 150 ml capacity. 1/4" Ar gas inlet on the top with max. pressure 2 MPa Max. heating temperature 450 °C +/- 1 °C 2. Heatable slot die: Extrusion width: 150 mm Slot-die gap: 0.2 , 0.5, and 1.0 mm adjustable by including shrim Max. heating temperature: 350°C +/- 1 °C 3. Heatable blade with 4 sides, fixed gap. Fixed gap in 4 sides: 10 ,15, 20, 50 um ( other size available upon request) Max. heating temperature: 300°C +/- 1 °C Heatble Vacuum Bed The vacuum bed is made of Aluminum alloy ( SS316 is available at an extra cost) Dimension: Width 250 x L 400 mm Effective coating area: Width 150 x L 300 mm Vacuum hole size: 1 mm diameter Surface flatness: < 5 microns Max. heating temperature: 200°C +/- 1 °C One moving mechanism is built into the bottom of the bed Moving speed of the cating: 10-100 mm/s, adjustable One oilless vacuum pump is included for sucking the substrate from the bed Control Unit The control unit is built in the bottom of the vacuum bed, which can adjust the temperature of the vessel, slot-die, and blade, as well as the vacuum bed independently Adjust the moving seed of the coating fixture Optional: RS-485 port and operation software are available upon request at extra cost ( ~$800) to connect the device to a PC.. ( power cable with KF40 feedthrough is included to operate the device inside a glovebox) Dimension and Weight Size: L600*430*H500mm Weight: ~ 90 Kg Compliance CE Certified NRTL (UL61010) or CSA certification is available upon request at an extra cost Application note We cannot guarantee that the customer will be 100% successful in coating the Lithium film. The customer must find the best parameters by themselves through experimentation Lithium molten wets with the substrate is very important. You use OZ cleaning ot plasma etching to pre-treat the substrate to improve wetting capability The device shall be used in a glovebox with an Ar atmosphere.
